BACKGROUND AND PURPOSE An association between high lipoprotein(a) [Lp(a)] levels and positive Chlamydia pneumoniae IgG titers in coronary artery disease has been described. The possibility of predicting ischemic stroke by measurements of plasma Lp(a) and C pneumoniae antibodies was investigated. METHODS This incident case-control study included 101 case subjects (cases) who had suffered ische...

There is a well-known correlation between Herpes simplex (HSV) infection and erythema multiforme (EM). More recently, in Japan, it was found that Chlamydia pneumoniae (Cp) may promote the development of EM. All cases of Cp infection-associated EM that had been diagnosed in our clinic over the past two years (from 2011 to 2012) were analyzed. Cp infection was diagnosed on the basis of a signific...

Evolutionary considerations implicate infectious causation of atherosclerosis and help to resolve different risk factors as parts of an overall process of disease causation. An evolutionary approach also provides insight for the timing of research efforts to provide better control of pathogen evolution. In particular, evolutionary considerations emphasize the need to understand the transmissibi...

Chlamydia pneumoniae, a common human respiratory pathogen, has been associated with atherosclerosis in several seroepidemiological studies. Moreover, its presence in lesions of vessel walls has been demonstrated by culture, immunohistochemistry, PCR, and electron microscopy. In this study, we infected intranasally with C. pneumoniae New Zealand White rabbits which had been fed a normal diet. Re...

The in vitro susceptibilities of 11 strains of Chlamydia pneumoniae to azithromycin, clarithromycin, erythromycin, L-oflaxacin, and doxycycline were determined. Clarithromycin was the most active agent tested, with an MIC for 90% of strains and minimal chlamydiacidal concentration for 90% of strains of 0.03 microns/ml. The activity of azithromycin was similar to those of erythromycin and doxycy...

OBJECTIVES To investigate the in vitro activity of cethromycin, a new ketolide, against Chlamydia pneumoniae. METHODS The in vitro activity of cethromycin against 20 isolates of C. pneumoniae was compared with the activities of telithromycin, erythromycin A, azithromycin and clarithromycin against those isolates. RESULTS The MIC at which 90% of the isolates were inhibited and the minimal ch...

Elicited macrophages from 129sv mice with a functional deletion of the natural-resistance-associated macrophage protein 1 gene (Nramp1) were shown to be as susceptible as wild-type mice to infection with the Chlamydia trachomatis mouse pneumonitis and L3 serovars and to Chlamydia pneumoniae. Furthermore, the two groups of mice were shown to be similarly susceptible to an intranasal infection wi...

In vitro inhibitory effects of tea polyphenols on Chlamydia trachomatis and C. pneumoniae were investigated. A product of tea polyphenols, Polyphenon 70S was used. Chlamydial strains used were C. trachomatis D/UW-3/Cx and L(2)/434/Bu, and C. pneumoniae AR-39 and AC-43 strains. HeLa229 cells and HL cells were used for cultivation of C. trachomatis and C. pneumoniae, respectively. In the post-ino...

Chlamydia pneumoniae is a ubiquitous intracellular pathogen, first associated with human respiratory disease and subsequently detected in a range of mammals, amphibians, and reptiles. Here we report the draft genome sequence for strain B21 of C. pneumoniae, isolated from the endangered Australian marsupial the western barred bandicoot.
